The test results you have selected are very old and may not represent the current state of Wine.
Selected Test Results (selected in 'Test Results' table below)
What does not
The mouse pointer remains frozen on the screen once the game starts, but this is a minor (if any) distraction.
Also, when you exit the game, it gives an error box, but this does not affect the game itself.
What was not tested
A couple things need to be done before the game can run reasonably:
First, remove the 'video' directory from the game directory.
Second, download this patch (http://www.gsc-game.com/index.php?t=downloads&ss=299&s=patch) and install it into the game directory.
Third, go to 'configure wine', or 'winecfg' (they are the same thing). Go to 'applications' tab, and add the executable game file (for me, this was dmcr.exe). Where it says 'windows version', select 'windows xp'.
Fourth, go to the 'library' tab. Under 'new override for library' type in 'ddraw' and click 'add'. Under 'existing overrides', click on 'ddraw', and click 'edit'. Select the option for 'native then builtin'. Save changes and exit winecfg.
Sorry for the lengthy explanation, but it took me hours to figure all of this stuff out, and I thought I would save the next person some time.

A way around frozen screens

To circumvent the frozen screen problem, simply switch to and back from another virtual desktop (CTRL+ALT+DirectionKeys), this will unlock the mouse pointer within a second and without leaving/losing the game...
Yes, it works, but...

NVidia driver 304.64
wine 1.5.6 (yes, that one...)
Cossacks EW v1.15new
First of all, thank you Alen for the nice trick with ddraw.dll etc. Now, not only does Cossacks EW work, but also the other games from the same company, ie Cossacks-Back to War, Cossacks-The Art of War (I suppose, not tested that one), American Conquest, American Conquest-Fight Back and American Conquest-Divided Nation!
I can also confirm the black screen when trying to change the resolution (in EW only, the other games work fine), so unfortunately we are indeed stuck to 1024x768.
And finally, I can confirm the crash on exit, it happens to me too.
Apart from that, the game is perfectly playable.
Now, about wine...
It is indeed the version that comes with OpenSuSE 12.2 that works, ie the outdated version 1.5.6. The latest version of wine as of writing this comment, ie v1.5.20, does NOT work properly. It crashes or dies silently, some games don't load anymore, very unstable.
I installed manually the packages wine, wine-32bit, wine-gecko, libOSMesa8, libOSMesa8-32bit.
